PENDULUM CLOCK.

SPECIFICATION forming part of Letters Patent No. 373,727, dated November22, 1887.

Application filed J une 18, 1857. Serial No. 241,787. (No model.)

To all whom it may concern.-

Be it known that I, Hueo O. DEUss, a citizen of the United States ofAmerica, residing at Chicago. in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in PendulumClocks, of which the following is a specification. reference being hadtherein to the accompanying drawings.

This invention relates to pendulum clocks, having for its object theattachment of an auxiliary pendulum so connected with the regularpendulum that it will swing in opposite direction to the same, wherebythe two pendulums thus swinging past each other will not only mutuallyassist in controlling the speed of the clock-movement, but at the sametime the motion is pleasing and attractive to the spectator, who, byoptical delusion, imagines that the pendulums strike against each otherand then recoil from each other; and with the above object in view myinvention consists of the novel devices and combinations of devices,hereinafter described and specifically claimed.

In the accompanying drawings, Figure 1 represents a front elevation ofthe clock-movement having my improvements; Fig. 2, a sectional side viewof the same; and Fig. 3, an elevation of the escapementwheel, anchor,and pendulums detached.

Corresponding letters in the several figures of the drawings designatelike parts.

. A denotes the frame forthe clock-movement, that may be of any shapeand suitable construction to accommodate and form bearings for thearbors or axles of the several wheels and other parts, constituting aclock-movement that maybe of any well-known construction, and thereforeI shall only describe such parts of the'movement in direct connectionwith my improvements.

Bis the escape-wheel, mounted upon spindle b, and C is the anchor, thepallets of which alternately engage the teeth of the escape-wheel, andthat has a radial stem, 0, the upper end of which forms a segmentalloop, cl, placed over the axle, for limiting the vibration of theanchor, while its lower end has a sidewardlyprojecting pin, 6, movingbetween the prongs of a bifurcated cam, F, mounted upon a short shaft,f,to which shaftf the pendulum G is suspended, being rigid therewith. Thusarranged, each reciprocation of the pendulum G will allow the wheel B torotate the pitch of one tooth.

Upon shaft-f, I mount a pinion, g, and below such shaftf, to be paralleltherewith, I pivot, between the frame A and a suitable bracket, it,another shaft, 1', integral with auxiliary pendulum I, and upon suchshaft i, I mount a pinion, j, of same size with pinion g. The teeth ofboth pinions g andj meshing each other, the movement of one pendulum inone direction will transmit the reverse movement to the other pendulumin a manner that both pendulums will swing simultaneously in oppositedirections.

On account of the short angular swinging movement of the pendulumssegmental gears may be used in place of pinions g and j, or otherconnections may be formed between the two shafts f and 11 that willtransmit a reverse movement from one to the other, and therefore I donot desire to be restricted to the exact construction herein shown anddescribed.

WVhat I claim is 1. In a clock-movement, two pendulums, G and I,suspended on trunnions vertically in line and connected together bypinions or other suitable means, transmitting a reverse oscillatingmovement from one to the other, and one of the pendulums connected withthe anchor C of the escape-movement,substantially as and for the purposeset forth.

2. In a clock-movement,in combination with wheel B, anchor C, havingstem 0, with pin 6,

and with shaftf, carrying bifurcated cam F, and pendulum G of shaft 'i,carrying pendulum I, and being connected with shaftf by suitable meansfor transmitting a reverse oscillating movement, substantially as setforth.

In testimony whereof I affix my signature in presence of two witnesses.

HUGO O. DEUSS.
